Abstract
The present invention relates to electrical conductors for electrical transmission and distribution with pre-stress conditioning of the strength member so that the conductive materials of aluminum, aluminum alloys, copper, copper alloys, or copper micro-alloys are mostly tension free or under compressive stress in the conductor, while the strength member is under tensile stress prior to conductor stringing, resulting in a lower thermal knee point in the conductor.
Claims6
A method for the manufacture of an electrical conductor, comprising the steps of:
- feeding a strength member or multiple strands of strength members to a conforming unit suitable to work with conductive media, and the strength member being comprised of steel or is comprised of fiber-reinforced longitudinally extending composite material;
- extruding tubes and layers or other profiles from the conforming unit or other extrusion and folding machines, that sufficiently integrate onto the strength member(s) to encapsulate electrically conductive layers around the strength member(s) and form an electrical conductor;
- stranding additional layer(s) of aluminum or copper or alloy strands around the metal encapsulated strength member(s) to form an electrical conductor with more areas of conducting materials comprising aluminum or copper;
- and
- collecting the electrical conductor on a spool;
- wherein the conductors are compatible with conventional hardware crimping processes.
